A virtual eyeglass set may include a frame, a first virtual lens and second virtual lens, and a processor. The frame may mount onto a user's head and hold the first virtual lens in front of the user's left eye and the second virtual lens in front of the user's right eye. A first side of each lens may face the user and a second side of each lens may face away from the user. Each of the first virtual lens and the second virtual lens may include a light field display on the first side, and a light field camera on the second side. The processor may construct, for display on each of the light field displays based on image data received via each of the light field cameras, an image from a perspective of the user's respective eye.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A virtual eyeglass set, comprising: a frame configured to mount onto a user's head and hold a first virtual lens in front of the user's left eye and a second virtual lens in front of the user's right eye; the first virtual lens supported by the frame and the second virtual lens supported by the frame, each of the first virtual lens and the second virtual lens being supported by the frame so that when the virtual eyeglass set is mounted onto the user's head, a first side of the lens will face the user and a second side of the lens will face away from the user, each of the first virtual lens and the second virtual lens comprising: a light field display on the first side; a direction camera on the first side configured to capture a direction that the user's respective eye is facing; and a light field camera on the second side, the light field camera being configured to capture images from multiple viewpoints; and a processor supported by the frame, the processor being configured to construct, for display on each of the light field displays based on image data from the multiple viewpoints received via each of the light field cameras and the captured direction, an image from a perspective of the user's respective eye, the user's respective eye being behind the light field camera.
2. The virtual eyeglass set of claim 1 , wherein each of the light field cameras is configured to capture the image data.
3. The virtual eyeglass set of claim 1 , wherein each of the light field cameras includes a Fresnel lens.
4. The virtual eyeglass set of claim 1 , wherein each of the light field cameras includes multiple detectors and multiple lenses.
5. The virtual eyeglass set of claim 1 , wherein each of the light field cameras includes a single detector and multiple lenses.
6. The virtual eyeglass set of claim 1 , wherein each of the light field cameras includes multiple cameras.
7. The virtual eyeglass set of claim 1 , wherein: each of the light field cameras includes multiple cameras configured to capture the images from the multiple viewpoints; and the processor is configured to construct the image based on one of the multiple cameras for which the viewpoint is closest to a ray extending from the user's respective eye in the direction that the user's respective eye is facing.
8. The virtual eyeglass set of claim 1 , wherein each of the light field displays is configured to display the constructed image.
9. The virtual eyeglass set of claim 1 , wherein each of the light field displays includes multiple pixels covering at least ninety percent (90%) of the first side of the virtual lens.
10. The virtual eyeglass set of claim 1 , wherein each of the light field cameras includes multiple cameras covering at least ninety percent (90%) of the second side of the virtual lens.
11. The virtual eyeglass set of claim 1 , wherein each of the light field cameras includes a ten-by-ten (10×10) grid of cameras on the second side of the virtual lens.
12. The virtual eyeglass set of claim 1 , wherein the processor is configured to construct: a first image for display on the light field display on the first virtual lens from a perspective of the user's left eye based on image data received via the light field camera on the first virtual lens; and a second image for display on the light field display on the second virtual lens from a perspective of the user's right eye based on image data received via the light field camera on the second virtual lens.
13. The virtual eyeglass set of claim 1 , wherein the processor is configured to construct the image based on the image data received via each of the light field cameras and a visual acuity of the user.
14. The virtual eyeglass set of claim 13 , wherein: each of the first virtual lens and the second virtual lens further comprises an acuity camera on the first side configured to capture an image of the user's retina; and the processor is configured to determine the visual acuity of the user based on the image of the user's retina.
15. A virtual eyeglass set, comprising: a frame configured to mount onto a user's head and hold a first virtual lens in front of the user's left eye and a second virtual lens in front of the user's right eye; the first virtual lens supported by the frame and the second virtual lens supported by the frame, each of the first virtual lens and the second virtual lens being supported by the frame so that when the virtual eyeglass set is mounted onto the user's head, a first side of the lens will face the user and a second side of the lens will face away from the user, each of the first virtual lens and the second virtual lens comprising: a display on the first side; a direction camera on the first side configured to capture an image of the user's respective eye; and a wide angle camera on the second side; and a processor supported by the frame, the processor being configured to construct, for display on each of the displays by cropping images received by each of the wide angle cameras so that the display on each side of the respective lenses displays an image with a narrower angle than the respective wide angle camera so that the image represents a cone beginning from the user's respective eye, the user's respective eye being behind the respective lens.
16. A virtual eyeglass set configured to display, at each of a right lens and a left lens, an image based on captured directions of a user's eyes and data received via one of multiple cameras on an opposite side of the lens, the one of the multiple cameras being selected based on the one camera being closest to a ray extending from the eye of the user wearing the virtual eyeglass set in a direction that the user's respective eye is looking, the captured direction that the user's respective eye is looking being determined based on a direction camera on an opposite side of the lens from the multiple cameras.
17. The virtual eyeglass set of claim 1 , wherein the image constructed for each of the respective light field displays is from a vantage point that was not occupied by any of the viewpoints captured by the respective light field camera.
